[0059] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0060] like Figures 1 to 8 As shown, a cooking appliance is proposed according to an embodiment of the present disclosure, comprising: a shell portion 100, wherein the shell portion 100 has a first air duct 101 and a second air duct 102, the first air duct 101 being located on the bottom wall of the shell portion 100; a pot body portion 200 disposed within the shell portion 100, wherein a third air duct 103 is formed between the pot body portion 200 and the shell portion 100, at least a portion of the third air duct 103 surrounding the periphery of the pot body portion 200, and both the first air duct 101 and the second air duct 102 being connected to the third air duct 103; and an air supply portion 300 disposed within the first air duct 101.

[0061] The cooking appliance provided in this embodiment includes a housing portion 100, a pot body portion 200, and an air supply portion 300. The housing portion 100 has a first air duct 101 and a second air duct 102. The first air duct 101 is located on the bottom wall of the housing portion 100. The pot body portion 200 is disposed inside the housing portion 100, and a third air duct 103 is formed between the pot body portion 200 and the housing portion 100, communicating with the first air duct 101 and the second air duct 102. At least a portion of the third air duct 103 is located around the periphery of the pot body portion 200. The air supply portion 300 is disposed in the housing portion 100 and located within the first air duct 101. Based on the aforementioned configuration, the cooking appliance provided in this embodiment can utilize the aforementioned air ducts to provide space for gas flow. Therefore, in practical applications, after the cooking appliance finishes cooking the food, the air supply unit 300 can provide power for the gas to flow through the aforementioned air ducts. When the gas flows along the aforementioned third air duct 103, it can generate heat exchange with the pot body 200, improve the heat dissipation efficiency of the pot body 200, and enhance the gas flow in the bottom area of ​​the pot body 200, thereby increasing the heat dissipation rate in the bottom area of ​​the pot body 200. This can improve the heat dissipation effect on the heat-concentrated areas of the pot body 200 during the heat dissipation process, accelerate the cooling speed of the pot body 200 and the food inside the pot body 200, save energy consumption when the cooking appliance dissipates and cools the pot body 200, ensure the energy efficiency of the product, and help improve the user experience of the product.

[0062] It is understood that, in practical applications, the cooking appliances provided in this disclosure can be used as, but are not limited to, electric cookers, rice cookers, electric pressure cookers, etc.; the aforementioned shell portion 100 and the aforementioned pot body portion 200 can both be groove-shaped structures, that is, the shell portion 100 and the pot body portion 200 can both be hollow inside and open at one end. The internal space of the pot body portion 200 can be used as a cooking space, and the internal space of the shell portion 100 can be used as a accommodating space to accommodate the pot body portion 200; the bottom wall of the aforementioned shell portion 100 is also the side opposite to the open end of the shell portion 100, and the peripheral wall of the aforementioned shell portion 100 is also the part between the open end and the bottom wall of the shell portion 100. Similarly, the bottom wall of the pot body portion 200 is also the side opposite to the open end of the pot body portion 200, and the peripheral wall of the pot body portion 200 is also the part between the open end and the bottom wall of the pot body portion 200. The periphery of the pot body portion 200 is also the outer side of the peripheral wall of the pot body portion 200.

[0063] It should be noted that, taking the cooking appliance provided in this embodiment as an example when used as an electric pressure cooker, the cooking appliance can also reduce the internal pressure of the pot body 200 by lowering the temperature of the pot body 200. This helps to reduce the noise generated when the cooking appliance releases pressure, reduce the safety burden on the user during operation, and improve the user experience of the product.

[0064] It is understood that the aforementioned first air duct 101 and second air duct 102 are both connected to the third air duct 103. That is, the first air duct 101 is connected to the second air duct 102 through the third air duct 103. When the air supply unit 300 is running, one of the aforementioned first air duct 101 and the aforementioned second air duct 102 can serve as an inlet channel for gas from the external environment to flow into the housing unit 100. Correspondingly, the other can serve as an outlet channel for gas to flow out of the housing unit 100, which is specifically related to the air supply direction of the air supply unit 300. For example, when the air supply unit 300 supplies air from the first air duct 101 to the third air duct 103, the air supply unit 300 can draw in gas from the external environment through the first air duct 101 during operation and deliver it to the aforementioned third air duct 103 to utilize the low-temperature gas in the external environment to accelerate the heat dissipation of the pot body 200. After flowing through the third air duct 103, the gas can further flow to the external environment through the second air duct 102. In this case, the first air duct 101 can serve as the aforementioned inlet channel, and the second air duct 102 can serve as the aforementioned outlet channel; or, when the air supply unit 300 supplies air from the third air duct 103 to the first air duct 103... When air is supplied through duct 101, the air supply unit 300 can draw in gas from the third air duct 103 and discharge it from the shell part 100 through the first air duct 101 during operation, thereby increasing the gas flow rate around the pot part 200 and accelerating the heat dissipation of the pot part 200. Correspondingly, gas from the external environment can enter the shell part 100 through the second air duct 102 and flow to the third air duct 103 to replenish the third air duct 103 with lower temperature gas, ensuring the heat dissipation efficiency of the pot part 200. In this case, the first air duct 101 can serve as the aforementioned inlet channel, and the second air duct 102 can serve as the aforementioned outlet channel.

[0065] It is understood that the cooking appliance provided in this disclosure, by creating a first air duct 101 in the bottom wall of the shell portion 100 and providing at least a portion of a third air duct 103 around the periphery of the pot body portion 200, can, on the one hand, cause the gas in the third air duct 103 to flow around the periphery of the pot body portion 200 when the air supply portion 300 is running, and can increase the distribution range of the air ducts inside the shell portion 100, thereby increasing the contact area between the airflow and the pot body portion 200 and improving the cooling and depressurization efficiency of the pot body portion 200; on the other hand, it can place the first air duct 101 at a relatively low position, thereby leveraging the connection between the first air duct 101 and the third air duct 103 The structural positional relationship between the shell portion 100 and the pot body portion 200 facilitates the extension of the third air duct 103 further towards the bottom of the pot body portion 200. Consequently, during the operation of the air supply portion 300, it can improve the heat dissipation efficiency of the pot body portion 200's periphery while also improving the heat dissipation at the bottom of the pot body portion 200. It is understood that during cooking, the bottom of the pot body portion 200 is usually heated, and the food inside the pot body portion 200 usually preferentially occupies the bottom space of the pot body portion 200. Therefore, the heat at the bottom of the pot body portion 200 is relatively concentrated. Based on the aforementioned arrangement, it helps to improve the overall heat dissipation efficiency of the pot body portion 200, providing favorable conditions for the rapid depressurization of the cooking appliance after cooking.

[0066] It should be noted that the first air duct 101 is provided on the bottom wall of the aforementioned housing portion 100, which means that one end of the first air duct 101 connected to the third air duct 103 is located on the bottom wall of the housing portion 100, and the other end of the first air duct 101 can be located on the bottom wall or the peripheral wall of the housing portion 100.

[0067] It is understood that by setting the air supply unit 300 within the first air duct 101, the cooking appliance provided in this disclosure can keep the air supply unit 300 relatively away from the bottom area of ​​the pot body 200, thereby avoiding the air supply unit 300 being affected by the heat of the pot body 200. This helps to ensure the stable operation of the air supply unit 300 and reduces the requirements for the heat resistance of the air supply unit 300, thereby reducing the cost of using the air supply unit 300.

[0068] like Figure 1 , Figures 4 to 6 As shown, in some examples, the third air duct 103 includes: a first channel section 1031 formed between the bottom wall of the pot body portion 200 and the bottom wall of the shell portion 100; and a second channel section 1032 formed between the peripheral wall of the pot body portion 200 and the peripheral wall of the shell portion 100; wherein the first air duct 101 is connected to the first channel section 1031, and the second air duct 102 is connected to the second channel section 1032.

[0069] In this technical solution, the aforementioned third air duct 103 may include a first channel section 1031 and a second channel section 1032. The first air duct 101 is connected to the first channel section 1031, and the second air duct 102 is connected to the second channel section 1032. The first channel section 1031 is located between the bottom wall of the pot body 200 and the bottom wall of the shell 100, thus providing space for gas flow between them. Therefore, when the air supply unit 300 is operating, it can improve the heat dissipation efficiency around the pot body 200 while also improving the heat dissipation at the bottom of the pot body 200, thereby contributing to improved overall heat dissipation efficiency of the pot body 200. The first channel section 1031 provides favorable conditions for the rapid depressurization of the cooking appliance after cooking. When a heating device for heating the bottom of the pot body 200 is provided in the first channel section 1031, the airflow in the first channel section 1031 can also dissipate heat from the aforementioned heating device, preventing the pot body 200 from further absorbing a large amount of residual heat from the heating device after cooking. The second channel section 1032 is located between the peripheral wall of the pot body 200 and the peripheral wall of the shell section 100. When the air supply section 300 is running, the gas in the third air duct 103 can form a tendency to flow around the periphery of the pot body 200, which is conducive to increasing the contact area between the airflow and the pot body 200 and improving the cooling and depressurization efficiency of the pot body 200.

[0070] It is understood that the third air duct 103 is defined by the inner surface of the shell portion 100 and the outer surface of the pot body portion 200. The aforementioned first channel segment 1031 and the aforementioned second channel segment 1032 can be distinguished by the bottom wall of the pot body portion 200. The first channel segment 1031 is defined by the inner side of the bottom wall of the shell portion 100, the outer side of the bottom wall of the pot body portion 200, and the inner side of the peripheral wall of the shell portion 100 located between the inner side of the bottom wall of the shell portion 100 and the outer side of the bottom wall of the pot body portion 200. Thus, in practical applications, the shape of the third air duct 103 is constrained by the shape of the shell portion 100 and the pot body portion 200.

[0071] like Figures 1 to 8As shown, in some examples, the housing portion 100 includes: a first housing 110, which has a groove-shaped structure; a first air duct 101 including a first ventilation hole 1011 opened in the first housing 110; and a second air duct 102 including a second ventilation hole 1021 opened in the first housing 110; a second housing 120 disposed within the first housing 110, which also has a groove-shaped structure; the first air duct 101 further including a third ventilation hole 1013 opened in the bottom wall of the second housing 120; and the second air duct 102 further including a fourth ventilation hole 1023 opened in the peripheral wall and / or bottom wall of the second housing 120; wherein, the pot body portion 200 is disposed within the second housing 120; the first air duct 101 further includes an installation space 1012 formed between the first housing 110 and the second housing 120; and an air supply portion 300 is disposed within the installation space 1012, with the air inlet side or air outlet side of the air supply portion 300 facing the third ventilation hole 1013.

[0072] In this technical solution, the aforementioned shell portion 100 may include a first shell 110 and a second shell 120. Both the first shell 110 and the second shell 120 may be groove-shaped structures. Accordingly, the second shell 120 is disposed inside the first shell 110, the aforementioned pot body portion 200 is disposed inside the second shell 120, and the aforementioned third air duct 103 is formed between the second shell 120 and the pot body portion 200. In practical applications, the aforementioned second shell 120 can be used as the outer pot of a cooking utensil, the pot body portion 200 can be used as the inner pot of a cooking utensil, and the first shell 110 can be used as the outer shell of a cooking utensil.

[0073] The first housing 110 has a first ventilation hole 1011 and a second ventilation hole 1021, and the second housing 120 has a third ventilation hole 1013 and a fourth ventilation hole 1023. The aforementioned first air duct 101 includes the aforementioned first ventilation hole 1011 and the aforementioned third ventilation hole 1013, and one end of the first air duct 101 connected to the third air duct 103 is located at the aforementioned third ventilation hole 1013, that is, the third ventilation hole 1013 is opened on the bottom wall of the second housing 120. The aforementioned second air duct 102 includes the aforementioned second ventilation hole 1021 and the aforementioned fourth ventilation hole 1023, and one end of the second air duct 102 connected to the aforementioned third air duct 103 is located at the aforementioned fourth ventilation hole 1023. When the air supply unit 300 is in operation, gas in the external environment can flow into the housing 100 through one of the first ventilation hole 1011 and the second ventilation hole 1021, and flow out of the housing 100 through the other.

[0074] An installation space 1012 communicating with the first ventilation hole 1011 and the second ventilation hole 1021 can be formed between the aforementioned first housing 110 and the second housing 120. Correspondingly, the aforementioned first air duct 101 also includes the aforementioned installation space 1012. The aforementioned air supply unit 300 is disposed in the installation space 1012, and the air inlet side or air outlet side of the air supply unit 300 faces the third ventilation hole 1013. When the air inlet side of the air supply unit 300 faces the third ventilation hole 1013, when the air supply unit 300 is in operation, gas can be allowed to enter through the first ventilation hole 1011. The first air duct 101 flows to the third air duct 103 through the third ventilation hole 1013, and then is discharged through the second air duct 102. When the air outlet side of the air supply unit 300 faces the third ventilation hole 1013, when the air supply unit 300 is running, the gas can flow from the second air duct 102 to the third air duct 103 and enter the first air duct 101 through the third ventilation hole 1013, and then be discharged through the first ventilation hole 1011. At the same time, based on the above-mentioned arrangement, it is also beneficial to improve the utilization rate of the internal space of the shell part 100 and improve the structural compactness and miniaturization level of the cooking appliance.

[0075] It is understood that the aforementioned installation space 1012 can be used to install some parts of the cooking appliance, such as electronic devices like the control board.

[0076] It is understood that the aforementioned fourth ventilation hole 1023 can be located on the peripheral wall of the second housing 120, thereby improving the positional matching between the fourth ventilation hole 1023 and the third air duct 103. This facilitates the rapid entry of low-temperature gas from the external environment into the third air duct 103 through the second air duct 102, or facilitates the rapid discharge of high-temperature gas from the third air duct 103 through the second air duct 102, thereby accelerating the gas flow rate and providing further assurance for improving the cooling and depressurization efficiency of the pot body 200; or, the aforementioned fourth ventilation hole 1023 can be located on the peripheral wall of the second housing 120. The bottom wall of the second housing 120 is such that the third ventilation hole 1013 and the fourth ventilation hole 1023 are both located on the bottom wall of the second housing 120, reducing the impact of structural openings on the overall strength of the second housing 120, which is beneficial to extending the service life of the second housing 120 and reducing the risk of damage to the second housing 120; or, the aforementioned fourth ventilation hole 1023 can be partially located on the peripheral wall of the second housing 120 and partially located on the bottom wall of the second housing 120, thereby widening the distribution range of the fourth ventilation hole 1023, improving the efficiency of gas flowing into or out of the third air duct 103, and further improving the heat dissipation efficiency of the pot body.

[0077] It is understood that the second ventilation hole 1021 and the fourth ventilation hole 1023 can be directly connected, or a gas channel can be formed between the first housing 110 and the second housing 120 to connect the second ventilation hole 1021 and the fourth ventilation hole 1023, so that the second ventilation hole 1021 and the fourth ventilation hole 1023 are indirectly connected. Accordingly, the second air duct 102 also includes the aforementioned gas channel. For example, the aforementioned gas channel can be, but is not limited to, the circumferential gap between the peripheral wall of the first housing 110 and the peripheral wall of the second housing 120. The first ventilation hole 1011 and the third ventilation hole 1013 are connected through the aforementioned circumferential gap.

[0078] like Figure 1 , Figures 4 to 7 As shown, in some examples, the air supply unit 300 includes a fan 310 disposed in the first air duct 101; wherein the air inlet side or air outlet side of the fan 310 faces the third ventilation hole 1013.

[0079] In this technical solution, the aforementioned air supply unit 300 may include a fan 310 disposed in the first air duct 101, so that the cooking appliance can use the fan 310 to provide power for the gas flow in the aforementioned air ducts. Correspondingly, the air inlet side of the aforementioned air supply unit 300 is also the air inlet side of the fan 310, and the air outlet side of the aforementioned air supply unit 300 is also the air outlet side of the fan 310. The air inlet side or the air outlet side of the fan 310 may be arranged to face the third ventilation hole 1013, so that when the fan 310 is running, the gas can flow from the first air duct 101 to the third air duct 103, or the gas can flow from the third air duct 103 to the first air duct 101, so that the cooking appliance can use the airflow to dissipate heat and reduce pressure on the pot body 200.

[0080] It is understood that the aforementioned fan 310 may be, but is not limited to, a centrifugal fan 310 or an axial fan 310. The specific type can be selected based on actual needs, and no further restrictions are imposed here.

[0081] It should be noted that, Figure 7 In the schematic breakdown of the cooking appliance, the pot body 200 and the peripheral walls of the first shell 110 are omitted.

[0082] like Figure 1 , Figures 4 to 7 As shown, in some examples, the air supply unit 300 further includes: an air guide 320 disposed between the fan 310 and the third ventilation hole 1013, the air guide 320 forming a guide channel 301, the cross-sectional area of ​​the guide channel 301 increasing along the direction close to the third ventilation hole 1013; wherein the cross-sectional area of ​​the third ventilation hole 1013 is greater than or equal to the cross-sectional area of ​​the guide channel 301.

[0083] In this technical solution, the aforementioned air supply unit 300 may further include an air guide 320 disposed between the fan 310 and the third ventilation hole 1013. The air guide 320 forms a flow channel 301, so that when the fan 310 is running, it can draw in gas from the third air duct 103 through the flow channel 301, or supply gas into the third air duct 103 through the flow channel 301, so as to promote the flow of gas in the third air duct 103 and dissipate heat and reduce pressure on the pot body 200; along the direction close to the third ventilation hole 1013, that is, along the fan 310 to the third ventilation hole 1013 The direction can be adjusted so that the cross-sectional area of ​​the flow channel 301 is increased, thereby enhancing the flow guiding effect of the flow channel 301 on the gas flow. When the fan 310 draws gas into the third air duct 103, the gas is gradually concentrated and the flow rate is increased as it approaches the fan 310. Alternatively, when the fan 310 delivers gas into the third air duct 103, the gas is gradually dispersed as it flows into the third air duct 103. This increases the contact area between the airflow and the pot body 200, thereby ensuring the flow rate of the airflow and further improving the heat dissipation and pressure reduction efficiency of the pot body 200.

[0084] Meanwhile, the cross-sectional area of ​​the third ventilation hole 1013 can be set to be greater than or equal to the cross-sectional area of ​​the guide channel 301, thereby reducing the resistance of gas flow between the third ventilation hole 1013 and the guide channel 301, which helps to reduce the flow loss along the flow path and avoids the bottom wall of the housing 100 from blocking the guide channel 301, which helps to ensure a smooth flow of air.

[0085] It is understood that the cross-sectional area of ​​the aforementioned third ventilation hole 1013 refers to the area of ​​the cross-section of the third ventilation hole 1013 perpendicular to its conduction direction, and correspondingly, the cross-sectional area of ​​the aforementioned flow channel 301 refers to the area of ​​the cross-section of the flow channel 301 perpendicular to its conduction direction.

[0086] It is understood that when the cross-sectional area of ​​the aforementioned third ventilation hole 1013 is greater than or equal to the cross-sectional area of ​​the guide channel 301, it means that the minimum cross-sectional area of ​​the third ventilation hole 1013 is greater than or equal to the maximum cross-sectional area of ​​the guide channel 301. For example, the cross-sectional area of ​​the aforementioned third ventilation hole 1013 can vary along its conduction direction or remain constant. When the cross-sectional area of ​​the aforementioned third ventilation hole 1013 varies along its conduction direction, and the cross-sectional area of ​​the aforementioned third ventilation hole 1013 is greater than or equal to the cross-sectional area of ​​the guide channel 301, it means that the minimum cross-sectional area of ​​the third ventilation hole 1013 is greater than or equal to the maximum cross-sectional area of ​​the guide channel 301. The number of the aforementioned third ventilation holes 1013 can be one or more. When the number of the aforementioned third ventilation holes 1013 is multiple, and the cross-sectional area of ​​the aforementioned third ventilation hole 1013 is greater than or equal to the cross-sectional area of ​​the guide channel 301, it means that the sum of the minimum cross-sectional areas of the multiple third ventilation holes 1013 is greater than or equal to the maximum cross-sectional area of ​​the guide channel 301.

[0087] like Figure 1 , Figure 4 and Figure 7 As shown, in some examples, the first ventilation hole 1011 is opened on the peripheral wall of the first housing 110, the fan 310 is a centrifugal fan 310, the air inlet side of the fan 310 faces the third ventilation hole 1013, and the air outlet side of the fan 310 faces the first ventilation hole 1011.

[0088] In this technical solution, the aforementioned fan 310 can be a centrifugal fan 310. Accordingly, the centrifugal fan 310 can be configured to intake air radially along the impeller and exhaust air axially along the impeller. The intake side of the fan 310 can face the third ventilation hole 1013, and the exhaust side of the fan 310 can face the first ventilation hole 1011. The first ventilation hole 1011 is located on the peripheral wall of the first housing 110. Based on the aforementioned configuration, when the fan 310 is running, it is convenient for low-temperature gas in the external environment to enter the first air duct 101 from the side of the housing 100. This helps to reduce the obstruction of the cooking appliance when it is intake air, improve the intake efficiency of the cooking appliance when it is dissipating heat and reducing pressure, and help to ensure the heat dissipation and pressure reduction effect of the pot body 200.

[0089] like Figure 5 and Figure 6 As shown, in some examples, the first ventilation hole 1011 is opened on the bottom wall of the first housing 110, the fan 310 is an axial flow fan 310, one of the air inlet side and the air outlet side of the fan 310 faces the third ventilation hole 1013, and the other faces the first ventilation hole 1011.

[0090] In this technical solution, the aforementioned fan 310 can be an axial flow fan 310. Accordingly, one of the air inlet side and the air outlet side of the fan 310 can be arranged to face the third ventilation hole 1013, and the other side can be arranged to face the first ventilation hole 1011. The first ventilation hole 1011 can be opened on the bottom wall of the first housing 110. Based on the aforementioned arrangement, when the fan 310 is running, the low-temperature gas in the external environment enters the first air duct 101 from the bottom of the housing part 100 and flows to the third air duct 103 along the circumference of the fan 310. This helps to reduce the turning of the airflow in the first air duct 101, reduce the frictional resistance of the airflow, reduce the energy consumption of the air supply part 300, and improve the heat dissipation and pressure reduction efficiency of the pot body part 200.

[0091] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, in some examples, a plurality of second air ducts 102 are spaced apart along the circumferential direction of the housing portion 100, and each second air duct 102 includes a plurality of arrayed second ventilation holes 1021 and / or a plurality of arrayed fourth ventilation holes 1023.

[0092] In this technical solution, the cooking appliance can be provided with multiple second air ducts 102, and the multiple second air ducts 102 are arranged at intervals along the circumference of the housing portion 100. Each second air duct 102 includes multiple fourth ventilation holes 1023, and the multiple fourth ventilation holes 1023 are arranged in an array. Based on the aforementioned arrangement, on the one hand, when the air supply unit 300 is running, gas can be allowed to flow through the second air ducts 102 at different circumferential positions, and the second air ducts 102 can easily connect with the third air duct 1 through the fourth ventilation holes 1023 at different circumferential positions. The connection between 03 helps the gas to flow around the pot body 200 in the third air duct 103, thereby ensuring the uniformity of heat dissipation in the pot body 200 and further improving the heat dissipation efficiency of the pot body 200. On the other hand, with a fixed total conduction area of ​​the second air duct 102, the fourth ventilation holes 1023 can be opened in a distributed manner to avoid opening excessively large and continuous holes in the shell part 100, which helps to reduce the weakening of the shell part 100 caused by the opening and ensures the structural reliability of the cooking appliance.

[0093] Alternatively, each second air duct 102 may include multiple second ventilation holes 1021, and the multiple second ventilation holes 1021 are arranged in an array. This allows the cooking appliance to draw in low-temperature gas from the external environment at different locations around the first housing 110 when the cooking appliance draws in low-temperature gas from the external environment through the second air duct 102, thereby improving the gas intake efficiency of the cooking appliance. When the cooking appliance discharges high-temperature gas through the second ventilation holes 1021, it can prevent high-temperature gas from being discharged through the same circumferential location of the first housing 110 for a long time. This helps to prevent the portion of the housing 100 near the second ventilation holes 1021 from suffering more severe thermal damage compared to other portions of the housing 100, thereby helping to ensure the overall structural strength of the housing 100 and extend its service life.

[0094] It is understood that the second air duct 102 may simultaneously include a plurality of second ventilation holes 1021 arranged in an array and a plurality of fourth ventilation holes 1023 arranged in an array.

[0095] It is understandable that the array form of the second ventilation hole 1021 and / or the array form of the fourth ventilation hole 1023 can be various, such as a ring array, a linear array, a rectangular array, etc. The specific form can be set according to actual needs, and no further restrictions are imposed here.

[0096] like Figure 8 As shown, in some examples, the third ventilation hole 1013 is located in the middle region of the bottom wall of the second housing 120.

[0097] In this technical solution, the third ventilation hole 1013 can be opened in the middle area of ​​the bottom wall of the second shell 120. Based on the aforementioned arrangement, when the air supply section 300 supplies air from the first air duct 101 to the third air duct 103, it facilitates the circumferential diffusion of the airflow to the shell section 100. Alternatively, when the air supply section 300 supplies air from the third air duct 103 to the first air duct 101, it facilitates the concentration of gas in the third air duct 103 to the air supply section 300. This also helps to improve the uniformity of the flow field in the shell section 100, providing a more reliable guarantee for the uniform heat dissipation of the pot body section 200 and the improvement of heat dissipation efficiency.

[0098] In some examples, the impeller of fan 310 is made of plastic material.

[0099] In this technical solution, the impeller of the fan 310 can be made of plastic material, which is beneficial to improving the lightweight level and manufacturing cost of the impeller compared with the impeller made of metal material, reducing the energy consumption of the air supply unit 300, and saving the cost of using cooking appliances.

[0100] like Figure 5 and Figure 8As shown, in some examples, the cooking appliance also includes: a heating unit 400 disposed between the air supply unit 300 and the bottom wall of the pot body 200 for heating the pot body 200; a temperature control unit connected to the heating unit 400; and a receiving groove 104 provided in the housing 100, in which the temperature control unit is disposed; wherein, one end of the first air duct 101 connected to the third air duct 103 is located in the middle region of the bottom wall of the housing 100, and the receiving groove 104 is spaced apart from the first air duct 101.

[0101] In this technical solution, the cooking appliance may further include a heating element 400 disposed between the air supply unit 300 and the bottom wall of the pot body 200. Based on the aforementioned arrangement, on the one hand, the cooking appliance can use the heating element 400 to provide heat to the pot body 200 during the cooking process to cook the food; on the other hand, when the air supply unit 300 is running, the airflow can flow through the heating element 400, thereby improving the heat dissipation efficiency of the heating element 400 and preventing the pot body 200 from absorbing a large amount of residual heat from the heating element 400 after cooking, which is conducive to further improving the heat dissipation and pressure reduction efficiency of the pot body 200.

[0102] It is understandable that when the third air duct 103 includes the aforementioned first channel section 1031, the heating unit 400 is disposed within the aforementioned first channel section 1031.

[0103] Meanwhile, the cooking appliance may also include a temperature control unit connected to the heating unit 400, so that the cooking appliance can use the temperature control unit to regulate the operating parameters of the heating unit 400 to adjust the heating state of the pot body 200 and improve the ease of use of the cooking appliance; the bottom wall of the shell part 100 may be provided with a receiving groove 104 spaced apart from the third ventilation hole 1013, and the aforementioned temperature control unit is disposed in the receiving groove 104, thereby improving the structural compactness of the cooking appliance based on the aforementioned arrangement.

[0104] In some examples, the cooking appliance further includes: a heating unit 400 disposed between the air supply unit 300 and the bottom wall of the pot body 200 for heating the pot body 200; an air duct control unit for opening or closing the second air duct 102; a first control unit connected to the air supply unit 300, configured to control the operation of the air supply unit 300 when the air duct control unit opens the second air duct 102 and the heating unit 500 is closed; and a second control unit connected to the air supply unit 300, configured to control the operation of the air supply unit 300 when the air duct control unit closes the second air duct 102 and the heating unit 500 is turned on; wherein the air supply unit 300 is used to supply air along the direction from the first air duct 101 to the third air duct 103.

[0105] In this technical solution, the first air duct 101 can be the aforementioned inlet channel, and correspondingly, the second air duct 102 can be the aforementioned outlet channel. The on / off state of the second air duct 102 can be controlled by the air duct control unit, and the air supply unit 300 can operate under the control of the first or second control unit. Based on the aforementioned configuration, during the process of the heating unit 500 providing heat to the pot body 200, the cooking appliance can shut off the second air duct 102 through the air duct control unit, thereby preventing the heat of the pot body 200 from being lost through the second air duct 102. Correspondingly, the air supply unit 300 can... The second control unit controls the operation of the air supply unit 300 to promote the flow of high-temperature gas in the third air duct 103 and form hot air that can act on the food in the pot body 200, which is beneficial to air frying the food in the pot body 200. When the heating unit 500 stops providing heat to the pot body 200, the cooking appliance can open the second air duct 102 through the air duct control unit and control the operation of the air supply unit 300 through the second control unit to promote the flow of gas in the third air duct 103 and accelerate the heat dissipation of the pot body 200 and the food in the pot body 200.

[0106] In some examples, the cooking appliance also includes: a lid portion disposed on the housing portion 100 for covering or opening the pot opening of the pot body portion 200; and a pressure relief valve disposed on the lid portion.

[0107] In this technical solution, the cooking appliance may further include a lid and a pressure relief valve. The lid is used to cover or open the pot opening of the pot body 200. During cooking, the lid can be used to cover the pot opening to ensure stable pressure inside the pot body 200. The pressure relief valve is located on the lid. When the lid covers the pot opening, the pressure relief valve is connected to the inside of the pot body 200. After cooking is completed, the internal pressure of the pot body 200 can be released by opening the pressure relief valve, so that the lid can open the pot opening.

[0108] It is understandable that the aforementioned pot opening is also the opening of the pot body 200.

[0109] Understandably, in practical applications, after cooking is completed, the air supply unit 300 can be used first to dissipate heat and reduce pressure in the pot body 200. After the internal pressure of the pot body 200 is reduced to a certain level, the pressure relief valve can be opened to release the residual pressure in the pot body 200. This helps to reduce the noise of the pressure relief valve when releasing pressure, avoids the user's anxiety caused by excessive noise, and helps to improve the user experience of the product.

[0110] Understandably, in practical applications, after cooking, the air supply unit 300 can be used to dissipate heat and reduce pressure on the pot body 200, so that the internal pressure of the pot body 200 is reduced to the external ambient pressure. This can avoid the user using the pressure relief valve and further reduce the noise generated by the cooking appliance when releasing pressure.

[0111] In some examples, the cooking appliance also includes a panel disposed on the peripheral wall of the first housing 110; wherein the first air duct 101 and the second air duct 102 are both arranged at intervals from the panel.

[0112] In this technical solution, the cooking appliance may also include a panel disposed on the periphery of the first housing 110, which is conducive to further improving the aesthetics of the cooking appliance. Furthermore, there is a gap between the first air duct 101 and the second air duct 102 and the panel, which is conducive to reducing the influence of the panel on the air intake and exhaust of the cooking appliance, ensuring the gas exchange efficiency between the cooking appliance and the external environment, and preventing the panel from contacting the high-temperature gas discharged by the cooking appliance, which is conducive to extending the service life of the panel.

[0113] It is understood that the aforementioned panel may include a panel body and a button assembly, wherein the panel body is disposed on the first housing 110, and the button assembly is disposed on the panel body so that the user can operate the cooking appliance through the button assembly; the panel may also include a display assembly disposed on the aforementioned panel body so that the operating information of the cooking appliance can be displayed through the display assembly.
